I have twitching all over the body and bones are crunchy cracking and poping more and more, sore joints some skin rash and red bumps like pimples showing up, also high blood pressure, some kind of gerd/ digestion problem going on, abnormal colored stool always green or yellow, sometimes with dark spots. Aches and pains come and go different spots all over body and get tremors/shakey feeling at times and heart beat at times seems to pulsate heavy. Also notice pulsations in abdomen also pain in upper left abdomen at and below ribs, tired/fiatigued now everyday, tightness trouble breathing at times, eye sight getting worse have been in hospital with atrial fibulation and chest pain was told low on potassium and doc blood work shows low side of vit b12 in system. what could be wrong with me?
